Beit known that i, Josnrrr Darn, Jr., a citizenV of the United States, residing at Moline, in the county of Roch island and State of illinois. administrator of the estate of Josnri-i' Darn, deceased, late of said Moline, illinois, hereby declare 'thatthe said JOSEPH Dain did invent certain new and useful lmprovements in Side-Delivery Rotary Rakes, of which the following is a specilication7 reference being had to the accompanying drawings,

This invention relates to side-delivery rotary rakes of the type employing a rotary reel arranged at an angle to the line of draft, such reel carrying several series of rake-teeth which are all maintained at the same angle so as to be properly presented to the hay that is to be raked into windrows. Such teeth are held in the desired uniform working position by the employment of suitable mechanism carried by the forward` reel-head, Vsuch mechanism ordinarily com.- prising a set of gears in connection with each tooth-bar and a single other gear that is in mesh with one of the gears of each of the said sets of gears. f

lllhile rakes such as referred to are provided with means at the rear side and adjacent to the outer end of the reel-frame for supporting such frame, and with relation to which such frame can be vertically adjusted -by causing it to rock about the main axle of the machine as an axis, it is sometimes of advantage to further and Vindependently adjust such frame vertically at its forward end, and it is the object of this invention to provide improved means for accomplishing this last-named adjustment, which object is attained by the devices and combinations of devices shown in the accompanying drawings and hereinafter particularly described. That which is believed to be new will be set forth in the claims.

In the drawings,- y

Figure l is a plan view of a side-delivery rotary hay-rake yin which the invention is embodied;

Fig. 2 is a detail, being a horizontal central section through the intermeshing driving.V gear and pinion-on the axle of the machine and the shaft of the rotatable reel, respectively., and showing also a' portion of the means by which the vertical adjustment of the forward or inner end of the reeliraine is accomplished;

Fig. 3 is a cross-section taken at line 3 3 of Fig. 2; and

Fig. -i is a detail, mostly in horizontal section, showing the inner or forward reelhead, a portion of the gearing carried ther by for maintaining the tooth-bars in proper position, and the lever and its pivoted sectorV that are employed when the gearing is to be adjusted to cause a change in the angle of the rake-teeth.

Referring to the several figures of the drawings, lO-l0 indicate a pair of carrying wheels mounted upon an axle ll. The wheels will be connected with the axle by any suitable means that will cause a rotation of the axle upon the forward movement of the machine, but which will not cause the axle .to rotate when the machine is backed. Such connecting means between an axle and a pair of wheels are common and well understood and hence are not illustrated. l2 indicates an Ordinary diagonally-disposed reel-frame that at its forward portion is so connected with the axle that it will rock about such axle as an axis when the frame is adjusted vertically by a relative movement between it and the usual rear groundcngaging supportingmeans. lt

is common to'provide one or more groundengaging devices 1n the rear of the reelframe and connect-ed with such frame in such manner as to permit the frame to be adjustable vertically withrelation thereto. In the construction shown two such devices are shown comprising caster wheels 13 each secured between a yoke lfrom which rises a vertical standard l5 pivotally connected with the frame, and from each of which extends a connection consisting partly of a chain member 16 and a linlr member 17, the two connections being attached to an adjusting lever mounted on the usual 'long truss member 18 that extends from the wheeled support back and over the reel-frame. By a stroke of the lever anV adjustment of the frame up or down relative to the groundengaging supports 13 Ywill be had. These adjusting devices are not illustrated in detail because, by themselves they form no part of my invention, and, indeed, may be lOO of any well-known construction. The details, however, of the particular two-wheel supporting meansv are clearly shown and described in the Letters Patent of the United States No. 1,313,880, dated August 26, 1919,

ranted upon the application of one Leon R.

' llausen. f

The reel that -is rotatably mounted in the frame 12 comprises two heads the inner or forward one of which is indicated by 19 and the outer or rear one by 20, such heads being connected together by a plurality of bars 21-three as shown-to which bars are 'shown in section oneof the sets of gears referred to, the outer one of the gears being indicated by 22 and thel gear that is in meshV therewith and which is journaled upon a pin made fast tothe head being indicated, by 23. The member 23 of each of the sets of gears referred to is in mesh with a smaller central gear 24 which is normally held fixed against rotation, but which by reason of being `mounted on a'cylindrical hub member,

.as shown, may be rocked in order to eect a change in the position of the severa-l toothbars so'as to incline the teeth carried thereby to the extent desired. There is shown in said Fig. 4 a lever and movable sector construction for accomplishing this rocking of the central gear, which lever and sector construction is shown 'and described in detail in the Letters Patent granted to Leon R.

lClausen, No. 1,283,674, dated November 5,

1918. vThe pivoted sector referred to is here indicated by' 25 and the lever that interlocks `Vtherewith and is connected at its inner endv with the gear 24 is indicated by 26.

27 indicates the usual central shaftof the reel upon Ywhich the reel-heads 19 and 2O are suitably secured so as to turn therewith,

Ysaid-shaft being preferably angular in crosssection, but suitably shaped at its ends t0 adapt suchends to be journaled in place in bearings-carried by opposite end portions of the frame. The shaft is driven in the usual manner by the intermeshing of a bevel gear 28 on' the axle 11 and a bevel gear 29 on the reel' shaft, but-whereas the said gear vhas heretofore been of ordinary construction,

the gear 28 that is here employed is of a special construction as is necessary in the carryingout of this invention, as will be made to appear hereinafter. 30 indicates a sleeve mounted loosely and eccentrically on the axle 11 and forming the bearing for one end portion of such axle. Around the eccentric sleeve 30 is a ring 31 from which extends Vupwardly an arm32 (see Fig. 3) that is bolted tothe overlying member of a portion ofthe main frame, and also formed lwith such ring and projecting rearwardly therefrom is another arm 33 that terminates in a sleeve 34 that surrounds and affords a bearing for the extended hub of the pinion 29 on the shaft 27, said hub sleeve member being held in place, as shown in Fig. 2, by a cotter pin, or in any other suitable manner. The portion of the frame to which the upright arm 32 isbolted is in the nature of an extensionof the main frame 12 and is indicated by 35, and, as shown, is the part that overlies and is connectedwith the axle 11. 36 indicates a -sleeve over that portion of the reel-shaft 27 between the pinion 29 and the inner reel-head and is simply intended as a spacingrdevice that. would prevent any movement inward of the pinion 29. 37 indicates a collar secured to the axle 11 to hold theeccentric lsleeve 30 inproper position on the axle.

The inner end of the eccentric sleeve has an annular flan e 38 at its inner end and resting upon suci fiange andv upon the outer surface of the eccentric sleeve so as to be rotatable thereon is a flange 39 formed with the said bevel gear 28. TheV inner faceof the gea-r 28 is provided with a deep annular recess, as clearly shown in Fig. 2, the any nular wall of which is toothed .as shown to form an internal gear with which meshes the teeth of a spur gear 40 located in said recess and rotatably mounted upon the shaft 11. Upon one face of the spur gear 40 are provided aY plurality of clutch teeth 41 adapted to interlock with the vteeth 42 of a clutch member 43 that is movablealongthe axle 11. The clutch member 43 is mounted upon a sleeve 44 thatis madel fast to `the axle 11, the clutch member 43being movably secured on such sleeve by means of one or more Vfeathers or keys 45. Theclutch `member 43 will be moved into andout' of clutching engagement with the spurV gear 40 by meansY of a` shifting lever 46 (see Fig. 1). 47 indicates a lever vrigidly aiiixed to the ohiter end of the :eccentric 'sleeve 30 by means yof which the said sleeve can be rocked, the lever havingV the usual spring latch for engaging :a segmental rack 48 car-V ried by the frame member 35 whereby the eccentric sleeve mav be locked in iio Now if it be desired to give the inner or for- -the eccentric and the ring surrounding it as to elevate or lower the frame, inasmuch as such frame is connected with the eccentric ring through the medium ot the vertical arm 32 and the rearwardly-extending arm 33. Such adjustment through the medium o1C the eccentric sleeve cannot, of course, affect the relation of the spur gear to the internal gear with which it meshes, and hence, of

course, such gear members are always in driving relation. Also, it will be noted that inasmuch as the gear shifting lever 26 and its pivoted segment are carried by the frame their relations to each other or to the vcentral gear 24- with which the lever con nects are not disturbed.
